Plant Services Features Founder Walter Boyd
30 MAR 2011
Because HVLS fan technology is relatively new (Walter Boyd, our founder, invented and then introduced the first HVLS fan in 1998), people still don’t understand how or why they work. Because they’re used to small, high-speed fans, people mistakenly believe that such a large, slow-moving fan simply cannot keep things cool. Hence, we often get questions from prospective customers like the following:
How can a such a slow moving fan keep my facility cool?
Do HVLS fans replace air conditioning?
How will these fans help us in the winter when we don’t need cooling?
Do they cool things other than people?
We’re happy to say that we have all the answers to these and other questions — straight from Walter Boyd’s mouth!

In this informative HVLS fan question and answer session for Plant Services, Walter talks about:
- The physics behind air movement
- Why larger fans like HVLS fans are much more energy efficient (it’s because they move larger volumes of air)
- Why they supplement (not replace) AC systems
He also discusses “de-stratification” — that is, the mixing of air, whether for cooling or warming, another topic that people ask questions about.
Walter explains everything in plain English — and if you still have questions, be sure to call us. We love talking to people about HVLS fans and how they can help you lower your heating and cooling costs.
